ABSTRACT
Objective:
To analyze the characteristics of pulse-step-sine (PSS) test in healthy people of different ages and to discuss its clinical value.Methods:
From July 10, 2018 to December 9, 2020, a total of 78 healthy volunteers, including 40 males and 38 females, were enrolled and divided into youth group, middle age group and old age group. The I Portal NOTC rotational-chair system (NKI) was applied for PSS detection to analyze the clinical characteristics of gain, phase, asymmetry, and slope of step and sinusoidal components. Statistical analysis was performed using SPSS17.0 software.Results:
In the same age group, there were no statistically significant differences in left and right step gain, slope gain and sine gain (All P values were greater than 0.05). Pairwise comparison between different age groups showed that there was no significant difference in the corresponding parameters between the youth group and the middle age group. Compared with young group, the old age group had a significantly lower step gain value in their left side (P<0.01) but not in the right side (P>0.05).The left and right slopes of the old age group were significantly lower than those of the young group and the middle group, and the differences were statistically significant (All P values<0.05).Conclusion:
The PSS test can detect bilateral and unilateral horizontal semicircular canal function with good tolerance in different age groups, better than the traditional rotational chair examination to determine the well-compensated unilateral vestibular function. PSS test is a new vestibular detection method.
